With the innovative designs developed by a team of ornithologists, architects, ecologists and engineers, the structures have narrow ledges and vertical sides to mimic the cliffs on which the kittiwakes normally nest. Each ANS comprises an octagonal topside with capacity for around 500 breeding pairs of kittiwake supported above the water on a single monopile. Individual nesting spaces are fitted with a sliding Perspex panel which will allow researchers to view the kittiwake from inside the structures without the birds being able to see them.
